1. Baptism of the Holy spirit doesn't mean indwelling of the Holy spirit, it means to empower someone to do something and this was only for the Apostles and the first century church who were the foundation of the church. They were empowered to preach the gospel and confirm it through signs and wonders.
2. Before Pentecost, the disciples were empowered by the Holy spirit and they did miracles in Jerusalem, but it was at Pentecost that they were empowered to preach also unto the gentiles. Tongues was a sign that they could now preach to the gentiles.
3. Indwelling of the Holy spirit is for the church or in the new covenant which only comes after the gospel was preached as a witness to all nations. When God indwells or makes a permanent residence in man, they become some form of Messiah and this is what we call knowing God face to face.
This is what they all waited for:
Heb 10:
24And let us consider how to spur one another on to love and good deeds.
25Let us not neglect meeting together, as some have made a habit, but let us encourage one another, and all the more
as you see the Day approaching. .....
36You need to persevere, so that after you have done God’s will, you will receive what He has promised.
37For,
in just a little while, He who is coming
will come and will not delay.
Rom 13:
11And do this, understanding the occasion. The hour has come for you to wake up from your slumber,
for our salvation is nearer now than when we first believed. 12The night is nearly over; the day has drawn near. So let us lay aside the deeds of darkness and put on the armor of light.
